In the previous article, we discussed “Polarized Sunglasses For Men In Style”. In this article, let’s talk about “How to choose the best blue light blocking glasses?”.
Nowadays, electronic products such as mobile phones and computers have become indispensable tools in our lives. While these high-tech products bring us convenience and fun, they also bring symptoms such as eye fatigue and myopia. Subsequently, blue light blocking glasses have also received everyone's attention. Anti-blue glasses are only suitable for people who use electronic products for a long time, not for people who are visually fatigued. Exposure to such unnaturally strong blue light for a long time every day, especially for teenagers and children, needs to pay more attention to the prevention of blue light. So, how to choose suitable blue light blocking glasses for kids?
What is blue light?
To prevent blue light, we must first understand what blue light is. The visible light with a wavelength range of 400-500 nanometers is called blue light. The light sources used in daily LED lighting and display products, including mobile phones, flat panels, and TVs, are mostly LED light sources excited by blue light. However, not all blue light is harmful to the human body. The human eye has an extremely low tolerance to blue light radiation in the 400-440 nanometer range. When the light intensity enters this threshold, photochemical damage is likely to occur. However, blue light radiation in the range of 459-490 nanometers is essential for regulating the human body's circadian rhythm and can affect the secretion of human melatonin, which in turn has an impact on the body's biological clock, alertness, and mood.(https://www.koalaeye.com/collections/blue-light-blocking-glasses)
Scientifically effective anti-blue light lenses must not only block harmful blue light but also cannot filter beneficial blue light. Most of the ineffective anti-blue light products on the market currently have two types of problems. One is that there is almost no protective effect on the blue light in the vulnerable zone of the human eye. The other is excessive protection, shielding the blue light spectrum in the beneficial band so that the blue light that is beneficial for physiological adjustment cannot enter the human eye. At the same time, the color of the lens is yellow, which is prone to color shift, aggravating visual fatigue, and even inducing the risk of myopia.
How to choose blue light blocking glasses?
Anti-blue light is necessary, but not all blue light can be filtered out, because blue light will interfere with the body's melatonin secretion after being over-filtered, thereby affecting sleep. Therefore, when choosing blue light blocking glasses, you should choose appropriately according to your own eyes.
For how to choose anti-blue glasses, consumers can distinguish from the color of the lenses. Generally speaking, a lens with a yellow color will have the effect of blocking blue light. But too dark lenses will affect the contrast sensitivity. Therefore, it is recommended that consumers choose moderately. In addition, consumers should also pay attention to whether the glasses products (lenses, frames) have conformity marks, etc. It is best to choose professional and well-known glasses shops to match glasses.
Pay more attention to protecting eye health
The protective effect of blue light blocking lenses requires professional equipment, such as spectrometers, to detect the transmittance in the blue wavelength band, and consumers cannot detect them on their own. For anti-blue glasses, if you consider buying, it is recommended that consumers choose to buy from a professional optical shop.
In the digital society, people are increasingly inseparable from electronic screens. In order to protect eye health, many people fall into misunderstanding that anti-blue glasses must be worn for a long time. In this regard, wearing anti-blue glasses also needs to vary from person to person and from time to time. If you watch the screen for a short period of time every day, and there are intervals, pay attention to rest, you do not need to wear anti-blue glasses. For people who frequently and continuously perform high-intensity visual tasks, it is recommended to wear anti-blue light glasses due to the possible medium and long-term cumulative effect of blue light.
Consumers must distinguish the specific situation when buying blue light blocking glasses, and then choose the best blue light blocking glasses that suit them. The right choice of fashionable and suitable anti-blue glasses can give your eyes full relaxation and comprehensive protection!
